Alden Hart, the creator of TinyG and the grblShield will be in town later this month and will give a talk at the 1/23/2014 CNC Build Club @7:00pm. The meeting is open to members and non-members. If you want to attend, please RSVP via Meetup.

The grblShield is a basic stepper motor driver Arduino Uno Shield. It is part of the standard parts list for the Shapeoko and there are thousands of these in the field. It can also act as a shield for the Arduino Due and run a special version of TinyG firmware.

The TinyG project is a multi-axis motion control system. It is designed for CNC applications and other applications that require highly precise motion control. TinyG is meant to be a complete embedded solution for small/medium motor control. Here are some of the main features of the v8 hardware.
